Australia will host the 2018 Invictus Games for wounded military personnel, Britain's Prince Harry announced on Saturday. More than 500 serving and former personnel from 17 nations will compete in the multi-sports competition in Sydney. Harry, who launched the first such games in London in 2014, said Australia was chosen because it was an iconic city with a proud military heritage and sports-mad fans. Athletes, who have been wounded, injured or become ill in service, will compete in both individual and team sports including swimming, archery, cycling, track and field, and wheelchair rugby. The games have been held in London and Orlando, and are due to be held in Toronto next year.
